Gary Cahill, a former Chelsea defender, has urged the current players to stick to their task and "leave everything out there" against Real Madrid in Tuesday's Champions League quarter-final meeting.

The Blues trail the opening leg 2-0 at the Santiago Bernabeu.

For the LaLiga winners, Karim Benzema and Marco Asensio scored.

When Chelsea was 3-1 down after the first leg against Napoli in 2012, they pulled off a spectacular comeback to win the trophy

When Chelsea was 3-1 down after the first leg against Napoli in 2012, they pulled off a spectacular comeback to win the trophy.

In a weird last-16 tie, a team led by Lampard and Cahill fought back to win 5-4 on aggregate.

"My message for what it's worth is to go out and give it your all, manage the game in the early stages and leave everything out there.

"If you leave everything out there, then you can look in the mirror and say 'I've done all I can do'. Leave everything on the pitch and give everything you can give," Cahill told BT Sport
